Characteristics

The resilient seat gate plate usually adopts the overall encapsulation process, and the sealing surface of the rubber material can compensate for small errors in the sealing surface through elastic deformation, achieving zero leakage. At the same time, the valve stem seal adopts an "O" - shaped sealing ring, usually with three layers, which can effectively prevent medium leakage.

Product Advantages

Good anti-corrosion performance: The inner and outer surfaces of the valve body and valve cover are generally treated with epoxy resin powder electrostatic spraying, and the gate is covered with rubber to prevent rusting of the valve body and corrosion of the medium.

Compact structure: The overall valve cover is designed with a concealed stem, and the valve stem moves inside the valve body, occupying small space and suitable for installation sites with limited space.

Easy to operate: The "O" - shaped sealing ring design reduces frictional resistance during opening and closing. The sealing ring can be replaced without stopping the flow of medium in the pipeline.

Good hygiene: The epoxy resin meets hygiene standards. The valve stem, valve stem nut, and other parts are made of stainless steel or bronze materials, suitable for drinking water systems.

Frequently Asked Questions

What is the main advantage of a resilient seat gate valve?

The primary advantage is its ability to achieve "zero leakage" sealing through the elastic deformation of the rubber-encapsulated gate, compensating for minor surface imperfections.

Is this valve suitable for drinking water systems?

Yes, the valve uses hygiene-grade epoxy resin coating and stainless steel or bronze internal components that are resistant to water corrosion, making it ideal for potable water.

What does "non-rising stem" (NRS) design mean for installation?

It means the stem moves internally within the valve body without rising vertically during operation. This makes the valve very compact and suitable for underground or space-limited installations.

Can the valve stem seals be replaced under pressure?

Yes, the "O" - shaped sealing ring design allows for replacement without stopping the medium flow in the pipeline, which significantly reduces maintenance downtime.

What is the standard of these valves?

These resilient seat gate valves are manufactured according to the BS5163 standard, ensuring international quality and compatibility for engineering projects.

How is the valve protected against corrosion?

Both internal and external surfaces are treated with electrostatic epoxy resin powder spraying, and the gate is fully encapsulated in rubber to prevent contact between the medium and the cast iron body.
